이전 버전에서 한 줄만 수정해봅시다.

저희는 이 함수의 매개변수 부분:

```Python
    first_name, last_name
```

을 아래와 같이 바꿀 겁니다:

```Python
    first_name: str, last_name: str
```

이게 다입니다.

이게 "타입 힌트"입니다:

{* ../../docs_src/python_types/tutorial002.py hl[1] *}


타입힌트는 다음과 같이 기본 값을 선언하는 것과는 다릅니다:

```Python
    first_name="john", last_name="doe"
```

이는 다른 것입니다.

등호(`=`) 대신 콜론(`:`)을 쓰고 있습니다.

        applyDefaultSettings(os, arch, buildJvm = BuildToolBuildJvm, timeout = 0)

        // Show all failed tests here, since that is what we are interested in

        assertEquals(5000, netServerEnum2.timeout);
    }

    /**
     * Test the reset method.
     */
    @Test
    void testReset() {
        String lastName = "LAST_NAME";
        netServerEnum2.reset(0, lastName);
        assertEquals(lastName, netServerEnum2.lastName);
    }

    /**
     * Test the writeSetupWireFormat method.
     */
    @Test

    void testServerInfo1GetName() throws Exception {
        NetServerEnum2Response.ServerInfo1 server = response.new ServerInfo1();
        String testName = "TESTSERVER";
        server.name = testName;
        assertEquals(testName, server.getName());
    }

    @Test
    @DisplayName("Test ServerInfo1 getAttributes")
    void testServerInfo1GetAttributes() throws Exception {

先ほどのコードから一行変更してみましょう。

以下の関数のパラメータ部分を:

```Python
    first_name, last_name
```

以下へ変更します:

```Python
    first_name: str, last_name: str
```

これだけです。

それが「型ヒント」です:

{* ../../docs_src/python_types/tutorial002.py hl[1] *}


これは、以下のようにデフォルト値を宣言するのと同じではありません:

```Python
    first_name="john", last_name="doe"
```

それとは別物です。

イコール（`=`）ではなく、コロン（`:`）を使用します。

    @Test
    @DisplayName("Test reset with key and lastName")
    void testResetWithKeyAndLastName() {
        // Reset with parameters should not throw exception
        assertDoesNotThrow(() -> transaction.reset(123, "testName"));

        // Transaction should be ready for reuse
        assertTrue(transaction.hasMoreElements());
    }

    @Test
    @DisplayName("Test hasMoreElements")
    void testHasMoreElements() {

     * Test getter and setter for componentName
     */
    public void test_componentName_getterSetter() {
        assertNull(factory.getComponentName());

        factory.setComponentName("testName");
        assertEquals("testName", factory.getComponentName());

        factory.setComponentName(null);
        assertNull(factory.getComponentName());

        factory.setComponentName("");

```Python
    first_name, last_name
```

থেকে এইগুলি:

```Python
    first_name: str, last_name: str
```

ব্যাস।

এগুলিই "টাইপ হিন্ট":

{* ../../docs_src/python_types/tutorial002.py hl[1] *}


এটি ডিফল্ট ভ্যালু ঘোষণা করার মত নয় যেমন:

```Python
    first_name="john", last_name="doe"
```

এটি একটি ভিন্ন জিনিস।

    boolean timed = isTimed(method); // Not going to bother with all timeouts, just 0ms.
    String testName =
        method.getName()
            + (fair ? "(fair)" : "(nonfair)")
            + (timed ? "(0ms)" : "()")
            + "/NotOccupying->IMSE";
    return new TestCase(testName) {
      @Override
      protected void runTest() throws Throwable {
        Monitor monitor = new Monitor(fair);
